In this study, we investigated the effect of excess sodium (Na) in a NaMnO2 structure using one-step heat treatment at 900 °C followed by quenching in liquid nitrogen (N₂). According to the X-ray diffraction (XRD) analysis, there was a competition between the monoclinic and orthorhombic phases, and we found that there were two monoclinic phases with similar structural properties. Therefore, we focused on revealing the formation of two isostructures of the monoclinic phase triggered by Na ions. We found that the lattice parameters and β angle changed from 113° to 105° in the samples with increasing Na content. Structural analysis of the powders using the XRD data was conducted using Rietveld refinement, and the phase ratios for all samples were calculated. The sample with x = 1.3 showed a 95% α-phase. To understand the formation of the two isostructures, we performed Density functional theory (DFT) calculations to examine their band structure, stability, and formation energy. A structural analysis of the excess Na-doped samples was performed using common techniques, and it was found that excess Na caused the formation of a coating on the grains in the form of sodium oxide. To validate this prediction, we conducted inductively coupled plasma mass spectrometry (ICP-MS), X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy coupled with energy dispersive X-ray (SEM–EDX) analyses using the basic properties of these techniques and their interactions with materials. In the second part of the study, we produced HC from locally sourced olive leaves and investigated their structural properties. The electrochemical properties of the electrode materials were examined using a half-cell configuration as electrodes with Na metal and a full-cell configuration using x = 1.3 cathode and HC anode. A direct-contact pre-sodiation strategy was used as the anode in the full-cell measurements. It was found that the full cells had initial capacity values of 150 mAh/g for the voltage range 1.5–4.3 V and 120 mAh/g for the voltage range 1.5–3.5 V.

Optimal rate of biochar application has positive effects on soil functional microbial abundance and agroecological function in a black soil of Northeast China

Microorganisms perform a crucial function in the biogeochemical processes that maintain soil quality. Nonetheless, the influence of biochar on soil microbial communities and their ecological functions remains poorly understood in black soils. To investigate this, a 2-year field experiment was conducted with four biochar application treatments: 0 t ha−1 (CK), 6 t ha−1 (BC6), 12 t ha−1 (BC12), and 24 t ha−1 (BC24). Microbial diversity and community composition under each treatment were assessed using high-throughput sequencing techniques. PICRUSt2 and FUNGuild were employed to predict microbial functional profiles. Compared to the control (CK), biochar addition led to notable shifts in both bacterial and fungal community structures. It also significantly enhanced bacterial α-diversity, as reflected by increased Shannon index, OTU counts, and Chao1 richness. However, a gradual decline in bacterial diversity was observed with rising biochar application rates. Taxonomic analysis revealed that biochar treatment significantly elevated the relative abundances of specific bacterial groups—such as Acidobacteria, Chloroflexi, Candidatus_Solibacter, and Bryobacter—as well as fungal groups such as Ascomycota, Zygomycota, Mortierella, Penicillium, and Fusarium. These effects were most evident under the moderate application rate (BC6). These microbial community changes may contribute to maintaining agroecological functions and soil health in biochar-amended soils. Regarding ecological functions, biochar application enhanced soil bacterial metabolic potential and saprotrophic fungal abundance, with more significant effects in the BC6 treatment, while reducing plant pathogenic fungi. This suggests beneficial effects on soil health maintenance and elemental cycling. Therefore, from the perspective of soil microbial community characteristics, biochar application positively influences black soil quality improvement. Considering environmental and economic benefits, a lower biochar application rate (6 t ha⁻1) may represent an optimal strategy for carbon sequestration, soil quality enhancement, and agroecological function maintenance in the studied system.

The effect of metal codoping on hydrogen storage has been meticulously studied in small cubic C8 nanocluster within the framework of density functional theory (DFT). Initially, a C8 nanocluster was doped with two Li atoms [C8(Li)2], achieving a hydrogen uptake of 15.5 wt% with an adsorption energy of 0.16 eV. Although this configuration demonstrates a high hydrogen storage capacity, its thermodynamic stability under ambient conditions is limited due to weak binding interactions between Li and H2 molecules. By introducing metal atoms that have stronger binding with the C8 framework, it is expected to enhance the overall structural stability. For that, we have chosen Na, K, Be, Mg, Ca, Sc, Ti, V, and Cr metal atoms along with Li to investigate the influence of codoping on hydrogen storage characteristics. The Ti- and V-codoped structures exhibited significant distortion of the C8 nanocluster during optimization primarily due to strong charge transfer, steric repulsion arising from the larger atomic radii of Ti and V, and partial bond breaking within the nanocluster framework and were, therefore, excluded from further calculations. The resulting codoped structures—C8LiNa, C8LiK, C8LiBe, C8LiMg, C8LiCa, C8LiSc, and C8LiCr—yielded hydrogen uptake of 16.1 wt%, 14.6 wt%, 11.2 wt%, 13.7 wt%, 12.4 wt%, 9.8 wt%, and 11.5 wt%, respectively, all surpassing the U.S. Department of Energy 2025 target of 5.5 wt%. Among these, the LiCr codoped C8 nanocluster exhibited significantly improved adsorption energies of 0.31 eV, which is within the ideal range of 0.2–0.6 eV for faster adsorption–desorption kinetics. Furthermore, Gibbs free energy corrections to H2 adsorption energy at various temperatures and pressures revealed superior thermodynamic stability of the C8LiCr structure, suggesting its promising potential for practical hydrogen storage applications. These results highlight the significant impact of metal codoping as a powerful strategy for enhancing hydrogen uptake, stability, and overall H2 storage performance in nanostructured materials.
